Where these units come from
Until the middle of the nineteenth century every town kept its own noon, set by the sun overhead, and nobody minded that the next town was four minutes behind. Railways ended that: a timetable cannot be written for a hundred local noons. Britain put its railways on Greenwich time in 1847, and in 1884 the International Meridian Conference in Washington chose Greenwich as the prime meridian and sketched the twenty-four-hour scheme we still use. Greenwich Mean Time was the world's reference until 1972, when Coordinated Universal Time replaced it: UTC is kept by atomic clocks and tied back to the turning Earth by leap seconds. The abbreviations on this page name standard time — the winter setting — which is why each one is a fixed number of hours rather than something that drifts through the year.
Where you meet them
A time zone becomes real the moment two people in different places have to agree on one moment: a call between offices, a flight that lands before it took off, a market that opens while you are asleep, a deadline written in somebody else's afternoon. Server logs, train and flight schedules and anything stamped with a time are kept in UTC precisely so that the question can always be settled, no matter whose clock was on the wall.
Questions people ask
What about summer time?
The offsets here are standard-time offsets, the ones a zone keeps in winter. Where summer time is observed, the same places move one hour further on for part of the year and take a different name: Central European Time becomes Central European Summer Time, Eastern Standard Time becomes Eastern Daylight Time. The switching dates are not the same in every country, and the two hemispheres change in opposite months, so for a date inside a summer-time period add an hour to whichever side observes it.
Why isn't every difference a whole number of hours?
Because offsets are decided by governments, not by geometry. India is half an hour off the hour, at UTC+05:30; Nepal is three quarters, at UTC+05:45; the Chatham Islands are at UTC+12:45. Any of these can be changed by law, and several countries have moved their offset within living memory.
Is the answer exact?
Where both units are defined in terms of one another by whole numbers, yes — the page says so above the figure, and the only rounding is in how many digits are shown. Where the ratio has no finite decimal, the page shows twelve significant digits and says the relation is approximate rather than pretending otherwise.

Reading an Eastern European time in London
A Greek shipowner proposes to talk at 15:00 Athens time. A Romanian supplier confirms a delivery for 09:30. A Finnish customer says the system will be down between 02:00 and 04:00. All of these are written on Eastern European Time, and a reader in London, Dublin or Reykjavik has to convert EET to GMT to know what they mean on a Greenwich clock. Subtract two hours: 15:00 EET is 13:00 GMT, 09:30 EET is 07:30 GMT, and 02:00 to 04:00 EET is midnight to 02:00 GMT. A reading in the first two hours of the day belongs to the previous date at Greenwich, so 01:20 EET is 23:20 GMT the day before.
Below you will find the rule, a pair of reference tables, a description of both zones, answers to the questions people most often ask about summer time, and cases from shipping to the Black Sea ports. Everything is calculated in your browser, and nothing is sent to a server.
The subtraction in detail
Take two hours away
Eastern European Time is UTC+2, and Greenwich Mean Time is UTC+0. Greenwich is therefore two hours behind. Subtract two from the EET hour each time you convert EET to GMT. If the result is negative, add 24 and move one date back. 00:50 EET gives −1:10, which is 22:50 GMT the previous day.
Eight readings
00:30 EET is 22:30 GMT the previous day. 06:15 EET is 04:15 GMT. 09:00 EET is 07:00 GMT. 12:00 EET is 10:00 GMT. 15:45 EET is 13:45 GMT. 18:00 EET is 16:00 GMT. 21:30 EET is 19:30 GMT. 23:45 EET is 21:45 GMT. The first is the only one on the earlier date.
The 02:00 landmark
When it is 02:00 in Athens or Bucharest, it is midnight at Greenwich. Any event that happens before 02:00 EET falls on the previous Greenwich date, and any later one falls on the same date. Keep that landmark in mind whenever you convert EET to GMT and you will avoid most date errors.
Eastern European Time
Territories
Greece and Cyprus, Bulgaria and Romania, Finland and the three Baltic republics, Ukraine and Moldova all use EET as their standard time. Egypt shares it. Cities include Athens, Nicosia, Sofia, Bucharest, Helsinki, Tallinn, Riga, Vilnius, Kyiv and Cairo. In total, well over a hundred million people live on this clock.
The summer variant
In the European members the clocks advance on the last Sunday of March and go back on the last Sunday of October, creating EEST at UTC+3. Egypt follows a different summer calendar, starting on the last Friday of April and ending on the last Thursday of October.
Greenwich Mean Time
Where it applies
GMT is the winter time of Britain and Ireland, the permanent time of Iceland, Ghana, Senegal and a number of neighbouring countries, and in computing a label for the reference that coincides with UTC. For a writer in Athens or Bucharest addressing readers abroad, GMT is the safest target.
The summer wrinkle
Between 29 March and 25 October 2026, London reads BST, UTC+1. A wall clock in London is then only one hour behind Athens, not two. The zero meridian itself is three hours behind EEST. Which of the two a reader wants depends on whether they read a clock or a log.
The two-hour gap and the working day
Office hours
An Eastern European office open from 09:00 to 17:00 works from 07:00 to 15:00 on the Greenwich clock. A British office open from 09:00 to 17:00 GMT works from 11:00 to 19:00 EET. Both are open between 09:00 and 15:00 GMT, which is 11:00 to 17:00 EET, a window of six hours.
Answers that arrive the same day
A message from a colleague who has to convert EET to GMT, sent from Bucharest at 16:00 EET, reaches London at 14:00 GMT, with three hours of the British day left. A message sent at 19:00 EET reaches London at 17:00 GMT, as the office empties, and the reply comes the next morning.
By air to London
A flight that leaves Bucharest at 06:00 EET, or 04:00 GMT, and takes about three hours and a quarter lands at 07:15 GMT. On the ticket the times 06:00 and 07:15 make the journey look barely over an hour long.
Questions about summer time
Does the gap change in summer?
Between wall clocks it does not. Britain and the EU members using EET make the same change on the same night: 01:00 UTC on the last Sunday of March and again on the last Sunday of October. In 2026 these nights are 28 to 29 March and 24 to 25 October.
What does the night look like?
On 29 March, a clock in London moves from 01:00 to 02:00, while one in Athens moves from 03:00 to 04:00. On 25 October both go back. At every moment, Athens is two hours ahead of London.
When is the answer different?
When your target is the zero meridian rather than a wall clock. In summer EEST is three hours ahead of UTC, so if you convert EET to GMT for a log in UTC you must subtract three. A clock in London, labelled BST, needs only two.
London and Piraeus: the shipping connection
Two centres of an old trade
Greek shipowners, mostly based in Athens and Piraeus, and the brokers and insurers of the City of London have worked together for generations. Telephone calls between them are scheduled around the two-hour gap. A fixture negotiation at 15:00 EET starts at 13:00 GMT, early enough for the London market to still be open.
Daily freight indices
The principal index of dry bulk freight rates is published around 13:00 London time. That is 15:00 on a Piraeus clock. Owners wait for it before they accept a bid, so a “convert EET to GMT” calculation on the cut-off for offers can decide whether a fixture is concluded the same day.
Black Sea ports
Constanța, Varna, Odesa
Ports on the Black Sea publish berth times in local time. A vessel due at Constanța at 06:00 EET is due at 04:00 GMT. A pilot who boards at 14:30 EET boards at 12:30 GMT. Charterers in London who track the cargo must convert each event if they want a single timeline.
Grain and oil cargoes
Loading commences in the morning and typically takes a day or two. A statement of facts that records “commenced loading 08:15, completed 21:40” on an EET clock needs two hours taken off each entry before the demurrage clock can be checked in London.
Cairo and the Suez Canal
The Egyptian clock
Cairo is on EET and, since 2023, observes summer time again, with its own calendar. Ships passing the Suez Canal are given convoy times in local time. A convoy slot given as 03:00 EET starts at 01:00 GMT, and one given as 15:00 EET starts at 13:00 GMT.
Between the two calendars
Between the European change on 29 March and the Egyptian change at the end of April, Cairo is on UTC+2 while Bucharest is on UTC+3 and London on UTC+1. Anyone who needs to convert EET to GMT for Cairo in those weeks should subtract only one hour for a London wall clock.
Football from Greece and Romania
Kick-off times
Evening matches in Greece and Romania usually kick off at 20:00 or 21:00 local time, which is 18:00 or 19:00 GMT. European club competitions are played on Central European time: a match at 21:00 CET is 22:00 EET, or 20:00 GMT. A British fan who follows an Eastern European side must keep both conversions in mind.
Weekend fixtures
Saturday afternoon games often begin at 17:00 EET, or 15:00 GMT. The match is therefore on the same clock hour as an English league fixture, which suits fans who want to watch two matches at once.
Helsinki and the Baltic business day
Working hours
Offices in Helsinki, Tallinn, Riga and Vilnius generally open at 08:00 or 09:00 and close at 16:00 or 17:00 local time. Those hours are 06:00 or 07:00 to 14:00 or 15:00 GMT. A London company that wants an answer the same day should write before noon its own time.
Online meetings
A video call at 10:00 EET starts at 08:00 GMT. If you convert EET to GMT for a regular weekly meeting, the 08:00 start will mean an early morning for the London participant and a mid-morning for the Baltic one.
Banking cut-offs in the region
Payments inside the EU
Banks in Romania, Bulgaria and Greece publish daily cut-off times for same-day transfers, commonly at 15:00 or 16:00 EET. In Greenwich terms those are 13:00 or 14:00. A British business that needs the money to arrive the same day should instruct the transfer by about lunch time its own time.
Foreign currency
Currency exchange offices in the region often close at 18:00 EET, or 16:00 GMT. A traveller who lands at 16:30 GMT should expect a closed counter and withdraw cash from machines instead.

How to read the table
Each row shows one Eastern European hour and the Greenwich hour that matches it, with a note when the date differs. The rows were produced by subtracting two hours, the same rule that applies when you convert EET to GMT.
Ten readings with minutes
Examples
01:05 EET corresponds to 23:05 GMT (previous day). 03:20 EET corresponds to 01:20 GMT. 05:50 EET corresponds to 03:50 GMT. 07:35 EET corresponds to 05:35 GMT. 10:10 EET corresponds to 08:10 GMT. 13:25 EET corresponds to 11:25 GMT. 16:40 EET corresponds to 14:40 GMT. 19:55 EET corresponds to 17:55 GMT. 22:15 EET corresponds to 20:15 GMT. 23:05 EET corresponds to 21:05 GMT.
The minutes stay the same
An exact two-hour difference leaves the minutes unchanged. If your answer shows different minutes, the input was misread.
What time of day is it in London?

Zones around Eastern Europe
The ladder
From EET, subtract two hours for GMT, one for Central Europe, and seven for New York in winter. Add one for Moscow and three and a half for Mumbai.
One moment on five clocks
When it is 12:00 in Bucharest, it is 10:00 in London, 11:00 in Paris, 13:00 in Moscow and 05:00 in New York. Writing these in an invitation spares readers a separate convert EET to GMT, and it also gives them a way to check your own sum.
Dated examples
January
On Saturday 24 January, 19:00 EET is 17:00 GMT. Neither side is on summer time.
Early April
On Saturday 4 April, 19:00 EEST is 17:00 BST. Both changed their clocks on 29 March.
July
On Saturday 18 July, 19:00 EEST is 17:00 BST and 16:00 UTC. If your target is UTC, subtract three hours.
November
On Saturday 14 November, 19:00 EET is 17:00 GMT. Both returned to winter time on 25 October.
Checklist: how to convert EET to GMT
Before
Read the label
EET is winter, EEST is summer. A source saying “Eastern European” may mean either.
Decide the target
For London’s wall clock subtract two hours all year. For true UTC, subtract three in summer.
After
Subtract two
If the result is negative, add 24 and use the previous date.
Test the landmark
02:00 EET must give midnight GMT.
Budget flights to British airports
Early departures, earlier arrivals
Low-cost carriers connect Bucharest, Sofia, Athens and Riga with Luton, Stansted and Gatwick. A morning flight that leaves Sofia at 05:45 EET leaves at 03:45 GMT. If the flight lasts three and a half hours, it lands at 07:15 GMT, on a ticket that prints the arrival as 07:15 and the departure as 05:45, so that the trip appears to last only an hour and a half. Only a traveller who does the “convert EET to GMT” calculation sees the real duration.
When to leave for the airport
Airlines advise arriving two hours ahead. For a 05:45 EET flight this means being at the airport by 03:45 EET, which is 01:45 GMT. Passengers who set their phone alarm in British time must set it for 01:45, not 03:45.
Tech hubs and British clients
Daily stand-ups
Software teams in Bucharest, Sofia, Kyiv and Tallinn often serve clients in Britain. A stand-up at 10:00 EET is at 08:00 GMT, which suits an early British project manager. A review with the client at 14:00 EET is at 12:00 GMT, just before the London lunch hour.
Releases and incidents
A release scheduled for 21:00 EET takes place at 19:00 GMT, when the British support team has gone home. Teams that want a fast reaction after a deployment prefer 12:00 EET, which is 10:00 GMT.
Exchange students and visiting scholars
Timetables for term
Students from Eastern Europe at a British university see lecture times in GMT. A lecture at 09:00 GMT is at 11:00 on the clock they used at home. Calls to family are easiest between 16:00 and 18:00 GMT, which is 18:00 to 20:00 EET, after lectures and before the family goes to bed.
Deadlines
An application deadline of 23:59 EET on a given date is 21:59 GMT on the same date. A student who submits from Britain at 22:30 GMT has already missed it by half an hour.
Mistakes when you convert EET to GMT
Subtracting one hour
One hour separates Central Europe from Greenwich. Eastern Europe is two.
Adding instead of subtracting
London is behind Athens. If the answer is bigger than the input, you added.
Keeping the date
01:30 EET is 23:30 GMT the previous day. Do not copy the original date.
Ignoring summer
In summer the distance to the zero meridian is three hours. To a London wall clock it is two.
Frequently asked questions
What is the difference between EET and GMT?
Two hours, with EET ahead.
What is the formula to convert EET to GMT?
EET hour minus two, adding 24 if the result is negative.
What is 18:00 EET in GMT?
16:00 GMT.
Does the gap change in summer?
Between wall clocks, no. To true UTC, it grows to three hours.
Is my input saved?
No. It stays in your browser.
